To aZZ whom it may concern: .j I 3 Be it known that 1, Helena G. INsLnna citizen of the United "States, and a resident of Roselle,in the county of Union andSt'ate -5 of New Jersey, havemvented' a new and usefullmprovement in Wabblers, of which-the following is a specification.

This invention relates generally to'means for operatively connecting a rotating dI'lV-r 1 0 'ing element" to a rotatablydriven one, and

- two must be capable of vpermitting"such V 2 changes in relative position Wh1l8' at the same "time assuring an effective driving action. 7 Besides changes in the angular relation :between the roll and its shaft',var1ous ad ustments change their relativeposition longi .tudinally of each other, consequently the wabbler must accommodate itselfwand" properly function under all of these conditions. Here tofore, in order to secure the necess'a-ry ac commodation referred to, the/ends of the wabbler connected to the driving shaft andthe roll shaft'have engaged the" same with a very loose fit, and'the changes in the relativeposition of the parts permitted by the lost motion existing therebetween; On account of this lost mot-ion, the mills-so equipped have been necessarilyquite noisy, with considerable wear on the w'abbler, and have required additional power .to operate under these conditions. though objectionable with the smaller mills, become pronounced in of largesize.

It is an ob noted above, in which the lost-motion and wear between the parts is reducedto a mini-1 mum, which will operate with comparative.-

1y little noise, and one which will readily at a reasonable cost, which maybe easily These disadvantages, a1

The extremity of he roll shaft 8 lSfOEPQt-Etl as a head 15Isi1nilar to thehead 12 of the driving shaft, 5, with "the exception of the shoulder .13, losing provided with the oppositely disposed. spherically":curved zsn-rth oppositely disposed flat surfaces 15, p: i i- V Coop'erating tv th the .iextremitres of both the driving" shaft and the rollshaft 1s a U-shaped yoke the tyolre associated :With' the driving shaft losing indicated generally at 16. and that'asso'eiated with the roll shaft at 17. Both of these yokc's are identical in Construction, Varying only insize,'.and-it will therefore be necessary to describe in detail but one of them.

The details of the yoke are clearly illustrated in Fig. 3 of the drawings; The

yoke as a'jwhol'e is substantially Ussh'apedp th'e'le'g portions of which are in'th'e form of elo'ngied lugs 18, 18 connected at their centers by means of a bridge piece 1.). The

ends of thelugs are slightly enlarged 2o; 20f, having their outer surfaces 21, "121' cylindrically curved, and their inner surfaces 223*22 flat, with one of the flat surfaces disposed upionithe' oppositeside of the enlarged portion of the lug from'each of'the eylindrically curr-edzsurfa'ce's. All of these surfaces are intended as bearing surfaces and are suitably machined for this purpose,

and in order toyinake definite their leverage about the yoke center, the portion, intermediate :the enlargements 20, 20f is; purposely of longitudinal displacement, and

.tuhular casing comprising the sections 23,

'23" which are held in assembled relation by a phu al ty ,of holts such as shown at 24. In the form illustrated in the drawings this 7 casing is somewhat larger at the end adjacent the roll shaft 'thzl'llifit its opposite end correspond ng to the 'Clliffl'GDCGS in size between the -3-o'kes .16 and 14. lt {is understood however that such difference in size between the opposite ends is not .2111 esscntial of the inventioin and is merely inci dental to the variation insr/e of the two yokes employed inxthe cons ction illustrat-ed.

'l he casing may be strengthened :hy the employment 'of' in rnal annular 11655151161 as indicated I desired, and the inner wall thereof is s 'i y eonstrnoted at each end with suitable bearingksnrfaces for the purpose of nnchoring the yokes for {rocking movement in a single plane, withontdanger for cooperation "niith the spherically curved portions at the extremities of the shafts to per: niit rocking movement 'hetw en the casing and shafts While :a-tithe same time prevent ing relative lateral movement therehetween.

As illustrated -infhlig, 2,:the 'innenWall-of e the casing is provided withwa eylind-rice'lly curved hearing surface 26*Wl11' 3l1 .15 adapted to cooperate With the "curled/surface 21 'on the yoke 16, :and the opposite enlarged cnd'of the leasing is likewise ,prori'ded with the cylindrioallycurved surface 27 which coact-s in :a similar manner with the curved surfaeeon' the yoke 17 lying :in abuttingqrelation therewith. For the purpose of -simplicitmwbut one quarter the .cntire, inner surface of the .ca-singshasbeen i'llustratec'l, as in Fig. 2, it being understood, i-hmvever,v

that four .oylindrieally curved hearing =sur- I faces are provided at caeh end of the ea-sing; for cooperationiwith the four cylindrically curved hearing snrfacesroneach 'of th'e yokes. The'rclatwe disposition ofith'e cyr,

lindrically curved bearing surfaces noon :the

interior of the casing at the smaller end thereof. is clearly shown in G of the i drawings these surfaces being indicated irespeetively at .26 "26, 12"? *and 26,' likewise, the relative dlsposltion of the iseveraltyhndi'i'cally curved bearing surfaces at the en larged end of the casing is shown in Fig. I

and indicated respectively :at 27, 9?, 2T and 27.

The yokes 16 andl'? may be readily positioned within the Wahhler cap or casing upon separation of the "two -sections 23, 23,

which when bound into intimate contact,

ings, will positively anchor the yokes with in the casing, operativelyv connect "the same,-

prevent relative longitudinal movement with respect to "the casing, while at the same time permitting free rocking movement of the yokeswithin the casingin a's'ingle plane,

thatis in the plane'of thepaper, as viewed in Figs lc and 7.. l The distancetbetween the flat bearing sur faces 12 corresponds to the distance be tween the flat bearingsurfaces 22 and 22',

of the yoke, andthediameter of the partial .phere formed by thei curved surfaces12 is substantially equal to the diameter the. opening atthe end of the casing. The size" of head 15 at the extremity of the roll shaft corresponds in like manner to the dimensions between the flat surfaces of the yoked? and thesize of the opening at the adjacent end of the casing. tween the opposite flat bearing surfacesof theshaft'extremities with the nner bearing surfaces of the yokes, longitudinal sliding movement between the shafts and theyokes is readily permitted, and the cooperation .therebetween together with the coaction be} tween the curved portions of theextreinities with the casing also permit rocking move; ment of the headed extremities of the shafts" within the casing. Due to the vneat fit between the several bearing surfaces,,the 'slidn ing movement as well as the rocking movement, both between the .yokes and casing and between the headed extremities of the shaft and the casing, takes place with substantially no lost motion between the com tacting parts.

against the ring 14;, and is-limited in its downward travel'thereby, so as to maintain the several parts within theirproper lnnits foreifective operation. 3

In 4' the driving shaft 5 vi roll shaft 8 have been shown with their axes lustrated therein.
